i have found this bug on 67b, and i jsut see that they are on 68 too
find this line in battleupdate.php
PHP Code:
$userattbonus = $DB_site->query_first("SELECT $id FROM items_user WHERE userid='$opponent[userid]'");
and replace by
PHP Code:
$userattbonus = $DB_site->query_first("SELECT $id FROM items_user WHERE userid='$user[userid]'");
Because he take damage bonus item from your opponent and not our item.
i have do a test, a friend with damage item and me with nothing.
i got all damage bonus item from my friend, and my friend get 0 damage bonus.
i think it's a bug.
